[Chapter 329] Got it, housekeeper! (First update)
"I know, the things I've done have left you with a very negative impression of me. I'm not asking you to forgive the person I was in the past.

From now on, I won't do that anymore."
As for saying Ji Rui is slow, or a fool, it really only applies to matters of the heart, or more accurately, when it comes to Le Tong.
He's genuinely intelligent and perceptive, with his own methods for handling people and matters. Otherwise, he couldn't have taken control of the Ji Family from Mr. Ji in just a few years.
